Automatic detection of impact craters on Al foils from the Stardust interstellar dust collector using convolutional neural networks

Logan Jaeger, Anna L. Butterworth, Zack Gainsforth +9

NASA's Stardust mission utilized a sample collector composed of aerogel and aluminum foil to return cometary and interstellar particles to Earth. Analysis of the aluminum foil begi…

Fine-grained Material Associated with a Large Sulfide returned from Comet 81P/Wild 2

Zack Gainsforth, Andrew J. Westphal, Anna L. Butterworth +10

In a consortium analysis of a large particle captured from the coma of comet 81P/Wild 2 by the Stardust spacecraft, we report the discovery of a field of fine-grained material (FGM…

Measurement of the Oxidation state of Fe in the ISM using X-ray Absorption Spectroscopy

Andrew J. Westphal, Anna L. Butterworth, John A. Tomsick +1

The oxidation state of iron in the interstellar medium (ISM) can provide constraints on the processes that operated on material in the protosolar disk. We used synchrotron-based X-…

Oxygen Isotopic Composition of Coarse- and Fine-grained Material from Comet 81P/Wild 2

Ryan C. Ogliore, Kazuhide Nagashima, Gary R. Huss +3

Individual particles from comet 81P/Wild 2 collected by NASA's Stardust mission vary in size from small sub-m fragments found in the walls of the aerogel tracks, to large fragme…
